★Industry-First "Pair App"
Pairism has two apps: one for women and one for men. (The app's features and design differ between the men's and women's apps.)
(To share data, your female partner must also install the "Women's App.")

★How to Use - Pairing (Partner Registration) -
When you pair with your female partner, her registered period and future ovulation dates will be synced and shared with the "Men's App."
This allows men to understand information unique to women, such as their menstrual cycle and fertility (safe and unsafe days), helping them understand the rhythms of a woman's mind and body.

★Simple Design
The app features a simple, timeless flat design and an easy-to-understand, intuitive interface. We've focused on streamlined functionality and original Pairism specifications.

★Main Features
①Period Prediction/Ovulation Prediction
Once you've paired with your partner, you can instantly check your expected period, ovulation, and other dates by simply launching the app. You can check your menstrual cycle, which is unique to women and difficult to ask about directly with men, such as fertile periods (dangerous days), infertile periods (safe days), premenstrual symptoms (PMS), and menstrual discomfort, and get advice on how to interact with your partner.

② Rhythm Color
What color is it today?
Pair Rhythm breaks down your menstrual cycle into small segments and displays your partner's mental and physical rhythms using colorful "rhythm colors."
Simply launch the app and see your partner's rhythm (condition) for that day at a glance♪

③ Calendar
This reversible calendar has two displays. Switch between your partner's "fertility" and "health rhythm" with a single touch. With over 300 pop icons, you can save schedules and notes, and use it to share schedules with your partner, manage anniversaries, and more.

④ Specialist Commentary
Female hormones play a vital role in women's health. The menstrual cycle (period) is controlled by the rise and fall of female hormones, causing changes in both your physical and mental health. At Pair Rhythm, specialists provide easy-to-understand explanations of medical knowledge about female hormones and the menstrual cycle to support male partners. Armed with accurate knowledge, you can use it as a reference for how you spend your day and interact with your partner.
